Re: 69 Chevelle L78 Buildsheet opinions
Any one of 5 different rear axle ratios were available when
the L-78 engine was ordered in a 1969 Chevelle Super Sport. These varied depending on the transmission ordered: <u>Manual-Auto.</u> 3:55---3:31/Standard-available w/or w/o Posi 3:31---3:07/Economy-available w/or w/o Posi (Posi excludes 3:07) 3:73---3:55/Performance-available w/or w/o Posi (3:73 only as Posi) 3:07 or 4:10---3:73 or 4:10/Special all Posi (excluding 3:07)

Re: 69 Chevelle L78 Buildsheet opinions
Rick - can you infer what the rear ratio is on this Chevelle given that the buyer selected an M21? I would say 3.55 but with the M21 selection, would it be another ratio?
